Lesson 2

1. Lesson 2 Good Production Practice #2 Use a veterinarian/client/patient relationship (VCPR) as the basis for medication decision-making.

2. Introduction • This lesson will help you to: • Identify the requirements of a VCPR • Understand the Food and Drug Administration’s (FDA) requirement prohibiting extra-label use of drugs in medicated feeds • Explain and understand over-the-counter, prescription, extra-label use and veterinary feed directive drugs Good Production Practice 2

3. VCPR • What is needed for a VCPR? • The veterinarian must: • Have assumed the responsibility for making medical judgments regarding the health of the animal(s) and the need for medical treatment • Have working knowledge of the animal and/or operation • Be readily available for follow-up and consultation • The owner/caretaker of the animal agrees to follow instructions of the veterinarian Good Production Practice 2

4. VCPR • Benefits of a VCPR • Your veterinarian will be able to: • Readily follow-up • Initiate a preliminary diagnosis much faster • Assist you with withdrawal times and recordkeeping • Provide “extra-label” drug use when appropriate Good Production Practice 2

5. VCPR • Involve your veterinarian • Regular herd checks • Timely and accurate diagnosis Good Production Practice 2

6. Medication Use • Label use • Using an animal health product exactly as it is stated on the label Good Production Practice 2

7. Medication Use • Extra-Label • When a veterinarian changes the medication dosage or any other instruction on the medication label Good Production Practice 2

8. Medication Use • Extra-Label • Your veterinarian may change: • Dosage • Frequency of administration • Route of administration • Duration of treatment • Indication or condition treated • Species or life stage treated • No one, not even a veterinarian, can prescribe the extra-label use of a medicated feed Good Production Practice 2

9. Medication UseExtra-label Use or Label-Use? The label says to give 5 cc of the drug, your veterinarian says give 10 cc. Your veterinarian suggests using a drug approved for cattle but not for swine on your pig. The label says treat your pig twice a day and you treat it at 8 a.m. and 8 p.m. Extra-labelUse Extra-labelUse Label Use Good Production Practice 2

10. Medication Use • Drug Compounding – • Mixing of two or more drugs to make a different medication • Compounding can only be done by your veterinarian and only when you have a VCPR Good Production Practice 2

11. Medication Use • Medicated feed • Feed containing an animal health product • Must be fed according to the label • Veterinary Feed Directive (VFD) • Category of antimicrobial drugs delivered in feed • You cannot buy, store or use VFD products unless you: • Have a valid feed mill license • Are a distributor of VFD feeds, or • Have a valid VFD issued by your veterinarian Good Production Practice 2
